Durham, N.C. — Duke University and North Carolina State University are the latest Triangle colleges to ban the use or storage of hoverboards inside residence halls.

The University of North Carolina at Chapel Hill and North Carolina Central University announced similar bans in the first week of the new year.

Duke's policy also bans hoverboards from university apartments, while N.C. State is prohibiting the devices throughout its Raleigh campus, including fraternity and sorority houses and academic buildings.

The electric scooters have come under intense scrutiny in recent weeks after reports that the batteries in some devices exploded or caught fire while recharging. The Consumer Product Safety Commission, which is investigating the fires, said hoverboards also are responsible for dozens of injuries after riders fell or crashed into objects.

Some retailers have stopped selling hoverboards because of safety concerns.
